Do tilite have adjustable angle backrests on their chairs as an option? I seem to remember they had this option a few years ago or maybe just a false memory...

And by the explaination on their order forms you have to calculate the dump of the seat to determine the backrest angle... That being said, If my new chair has 5" dump... the order form looks like I should have a backrest angle of 80 degrees.

I'm pretty sure I'm reading too much into this coz my innitial thought was that the amount of dump was irrelevant all you needed to know was how far you wanted to lean forward or backward... What's your thoughts?

If i want to get the ride designs (or another 3rd party backrest in the future) is there anything I need to be wary of... I've looked briefly into it, so I'm not too sure which backrest I will get in the future...

That's it for now, I'm sure more questions will present themselves as I delved deeper into this order form...

Thanks in advance.
